CHECK YOUR TRANSFER CASE OIL NOW. if you didn't know or never heard, the allison hd case has a tendency to get low on oil after 80 or so thousand miles with no apparent leaking. Just had a buddy put a $1400 transfer case in his because the oil got out some how. His had only 78000 miles. He drove it to the shop with no funny noises or actions. The tailshaft clip had dug through the top of the housing, filling the case with shavings. It only holds a little over 2 quarts, so low fluid is LOW. DieselForum has a lot on this subject if you need to read more because it appears to be a common thing. Just trying to keep anyone from having to spend a lot of unnecessary money. BTW if GM fluid is too expensive, Mobil 1 5w-30 is the safe alternative but it requires draining then refill. its a lot easier to remove the speed sensor from the tailshaft and pour it in from there, cause its a pain to get to the fill/check plug. Mine has 85000 DD,nonabused miles and the fluid was a quart low.
 
wow......im not a duramax owner, but i own a diesel, and low oil in anything can be bad. bump.
 
"Pump rub" is very common on the dmax tcases. Wearing a hole in the housing and causing problems.

Best bet is to just trade it for a dodge.
:flipoff2:
 
Yeah, and GM is not offering to cover this out of warranty, even though it affects every single t-case offered in the HD trucks. An aftermarket company is producing a piece that replaces these clips and eliminates the problem, but I can't recall who it is. I got rid of my '01 DMax in March of '08, so I got rid of two major pains in the ass...injectors and t-case. That truck was the biggest piece of shit ever!
 
Pump rub, very common, and affects all NP261/263s in all the 2500HD/3500s, duramax or gas.

I believe merchant automotive sells a fix for this, as does a few other companies.
 
IDK, while I own a dodge I'm starting to see some pretty nasty Dirtymax's out there in the Go Fast and Sled/Grudge Pullin world, granted it costs a decent amount more for a Dirtymax to get to a Dodge, but still, they are creeping up real quick . . .




IDK, I don't have much faith in Dodge's ever since I drove mine for total of 1 month of me owning it over a year now and its been broken and parked in the backyard all the rest of the time :shaking:


Anyone want to buy a midly disassembled Dually? :lol:

It only messed up because someone started F***in with it.
 
Just helped install a brandnew case in an 02 duramax. This one has 538000 miles though, with pretty much all of those miles pulling a 3 car wedge. Id say it was time for one!
 
I think the first jacked up t-case I saw was in an '03 Dodge dually. The chain rubbed a hole through the bottom of the transfer case :shaking: Luckily it was covered under warranty. I think it was a 271 or 273.....I don't remember.

Hadn't heard about the D-max t-case problems, but I wouldn't doubt it at all.
 
Last time I looked under a Ford, Dodge, Jeep, Chevy, Isuzu, Etc... they all used New Process TCases. The issue is with New Process not Chevrolet or Dodge. My Counter guy in Albemarle just had Galloways put a new one in his 02 max with 120k. It does indeed suck that the brand it is installed in dosent handle at least the parts if not the labor since they speced it out with that case. BTW... the Duramax is a friggin Isuzu engine. Ford uses International/Navistar and obviously Dodge is Cummins. None of them build a truck anymore, they provide a platform to bolt someone else's diesel drivetrain into.
Sucks that the big 3 are so lame these days. They can build a 500 hp vette or a super snake mustang, but not a decent diesel?

Isuzu helped design the dmax, GM engne plant builds it.
All new ford engines are prouced by Ford Engine company as the result of the Ford Navistar lawsuit, Ford retained the power stroke brand.
But your point is valid overall.
 
I hear ya' Skyhi... I guess i was just venting a little on the big 3. It sucks to pay that much for a truck that is likely to spend more time in the shop than on the road. IE... All the woes they have gone thru with the newer versions of the powerstroke since Ford took it back over. I look at the egr valve with a cooler located before the exhaust gets to the valve. DUH! Lets see what happens if we cool all this soot and carbon before it goes to the EGR valve. Naw! That wont clog up the valve every 30 to 50 thousand miles.:shaking:
You have to pull the cab off the truck to do any major engine repairs on most Fords. Its just plain ridiculous to those of us that make a living working on them. These engineers need to be forced to work on what they design. They should also be forced to drive one with 100k plus on them and pay for the upkeep. Then, maybe, you will see some real trucks being built.
Whew! I feel better!:lol:
 
I'm with ya nctom. But if the big 3's engineering department are run like the engineering department I manage, the engineers' hands are tied by executive management, board members that are terrified of the share holders, and share holders that want an immediate return on their investment. I'm an engineering manager for a publicly held company and I'm seen so many good ideas from my engineers get thrown out the window because upper management didn't think the public would go for it when they have no market research to support their opinion.

Rant over - thanks for listening.
 
One of my best friends is the head engineer over the engine shop at Hendricks Motor sports. Obviously they can put out a good product from concept to reality. But, like you said, it has to work from the top down. I wasnt throwing all engineers under the bus. I respect the heck out of most of them I have worked with. I agree with your comment that Managment is usually at fault for the crap that hits the streets. I would still like to get all the CAT engineers in one room and let them try to reach some of the stuff I have to work on.

Thats why I work for Cummins....if its a CAT it runs like a dog, LOL...

FWIW the 6.0 was an International product that was the real piece....
 
I hear ya' on the CAT crap. I dont have a religious type dedication to any one brand name. I have seen em' all put out some good and some seriously retarded product. 6BT is very solid, so Cummins has had a killer engine for quite a few years now. I tell my drag racing friends all the time, It dont matter what it says on the valve cover if you spend enuff time and money on it you can make it run hard.
 
Better check those cheap ass tranny cooling lines too,mine and several friends have fluid leaks with a possible blowout coming,of course GM wont warrant these lines after the 3/36 runs out....still LOVE my D-MAX!
